Canopy 900 MHz AP and SM User Guide
Issue 2 August, 2004 Page 10 of 16
The 900 MHz modules complement the other frequency bands offered. The 900 MHz modules can be used
to cover a larger area, albeit with lower throughput, than the other frequency bands. Depending on specific
operator requirements, they can be used to penetrate foliage, have greater range, or add additional
subscribers or additional overall throughput to a tower that is maxed out or can’t use another frequency
band due to interference or tower rights issues.
Operation
Set the Max Range parameter on the AP Configuration page to the distance of the furthest planned SM
from the AP cluster, as shown in Figure 1: Highlights of 900 MHz AP Configuration Page.
Important!
• Don’t over-set the range. Setting the range higher does not increase the power of the AP.
• Setting the range higher can reduce aggregate throughput.
• All 900 MHz APs in a cluster must be set to the same Max Range.
2.6 Modules and Antennas available
Description
900 MHz AP and SM modules are initially available as connectorized units connecting to connectorized
antennas. The following sections describe the module and three regulatory agency certified antenna
options.
Connectorized AP or SM
A connectorized 900 MHz AP or SM uses the same housing as a 2.4, 5.2, and 5.7 GHz module and has a 16
inch (approx 40 cm) cable with a male N-type connector for connecting to the antenna. It has a covered
Ethernet port and utility port (for alignment headset, sync cable to CMM2, or override plug), the same as
2.4, 5.2, and 5.7 GHz modules. Figure 2: Connectorized 900 MHz Canopy module and Flat Panel Antenna
shows a connectorized module connected to a flat panel antenna.
Connectorized Flat Panel Antenna
Motorola offers an external antenna, as shown in Figure 2: Connectorized 900 MHz Canopy module and
Flat Panel Antenna. The attributes of this antenna include:
• 10 dBi gain
• 8.8” x 8.1” x 1.6” (22.4 x 20.6 x 4.06 cm)
• 1.2 lbs (0.54 kg)
• vertical or horizontal polarization
• 12 inch (30.5 cm) cable
• female N-type connector
• 3 dB beam width approximately 60° vertical and 60° horizontal
